Skeletal and heart muscle-specific variant of the α subunit of nascent polypeptide associated complex (skNAC; encoded by NACA) is exclusively found in striated muscle cells. Its function, however, is largely unknown. Previous reports have demonstrated that skNAC binds to m-Bop/Smyd1, a multi-functional protein that regulates myogenesis both through the control of transcription and the modulatio...

عملگرهای پلاسمایی ابزار قدرتمندی جهت کنترل فعال جریان و لایه مرزی و نیز به عقب انداختن جدایش روی سطوح کنترلی هستند که در دهه­ اخیر بسیار مورد توجه پژوهشگران و مهندسین علوم هوافضایی قرار گرفته است. در ابتدا، ساختار استاندارد عملگرهای پلاسمایی (که شامل الکترود پنهان یک­ تکه­ ای می­ باشد) در پژوهش­­ ها و تحقیقات مورد استفاده قرار می ­گرفت، اما اخیراً ساختاری جدید از این عملگرها معرفی شده است که شام...

Tidal energy is the most foreseeable form of renewable energy. Tidal energy can be harnessed by tidal barrage, tidal fence and tidal current technologies. Present efforts are focused on diffuser augmented tidal turbines that exploit the kinetic energy of the tidal currents. The power output by a tidal turbine is directly proportional to the cube of velocity of incoming fluid flow. Thus, even a ...

In this numerical and statistical study, lift drag coefficient performances of NACA-0009 NACA-4415 airfoils were evaluated in accordance with various attack angle at constant velocity wind. Lift coefficients was numerically determined by computational fluid dynamics code ANSYS FLUENT. Analysis design calculations implemented using L16 orthogonal array based on Taguchi method. Angles airfoil typ...

Multiple numerical solutions of inviscid transonic flow over several airfoils exist at certain Mach number and angle of attack. Global linear stability analysis of the multiple solutions is conducted in this paper. Linear perturbation equations of the Euler equations around a steady-state solution are formed, an eigenvalue problem is then constructed using the modal analysis approach, then it i...

To perform a narrow anterior chamber angle (NACA) and angle-closure glaucoma (ACG) screening using the Van Herick’s method, the width of the peripheral anterior chamber depth (PACD) and corneal thickness have to be measured. These are the key parameters to identify a patient who may be suffering from ACG. Therefore, to develop an automatic screening algorithm for NACA and ACG based on slit-lamp...

Open-jet, hard-wall, and hybrid test section configurations are typically used in wind tunnel tests, aiming to represent the ideal free-flight condition. Each type requires special adaptations of experimental hardware specific correction methodologies that account for systematic measurement errors. Differently from previous research, this paper investigates comparability measurements performed ...
